Application filed August To all totem it may concern:

Be it lrnown that l, illimitata ld.' @neon a citizen ot the UnitedStates, residing at Uetroit9 county of W'a-yne, State oit Michigan, haveinvented a certain new and useul lm provement in letachable Cones torLaundry Extractors, and declare the following to be a full, clear, andenact description of the same., such as will enable others skilled inthe art to which it pertains to make and use the same, reference beinghad to the accompanying drawings, which term a part ot thisspecification.

c This invention relates to detachable cones "tor laundry eirtractorsand the object of the invention is provide a cone tor attachment to alaundry extractor to prevent tearing ot the clothes while the water isbeing entracte theretrom. This invention is adapted tor use in a laundryextractor comprising an outer cylindrical case in which a cylindricalapertured metal basket is rotatably mounted., the clothes being placedin the basket and the basket being rotated at a high rate or" speed toextract the water trom the clothes by centrifugal torce, the water beingthrown outwardly into the casing during rotation etiche basket. Thechief diiiculty with this type o extractor is that when the basket isloaded with wet clothes by inexperienced persons or one who is notexpert in operating an extractor, some of the clothes are placed 'toonear the center or extend across the-center and when the basket is soloaded and revolved at the extremely high rate 'speed which is customarywith extracltonoi this type the clothes extending across or near thecenter are torn due to the centrifugal orce applied by rotation ot thebaslret and tor reason laundries are put to bonsiderLN ense replacingthe clothes so torn. 'le rotore one o' the principal vobjects o thisinvention is to provide a device for preventing the tearing of clothesin this manner. Another difficulty in this typefoi extractor is thatshould the basket be loaded unevenly with more clothes -in one side thanin the other the basket tends to become eccentric in action whenrevolving at a high rate oit speed, thus quickly wearing 22, 192i..Serial No. 493,639.

the bearings and putting considerable strain on all parts ot themachine. Another object ot the invention is to provide a cone extendingupwardly in the center et the basket which spaces the clothes trom thecenter of the basket on all sides so het can be loaded much more evenlyand with greater speed and ease than heretofore. A further object of theinvention is to provide a cone of the character described which is lightin weight and which may secured in position in the center et the basket.rlhese objects and the several novel teatures ot' the invention in itspreferred torinare hereinafterH more fully described an claimed and thepreferred :torni et construc-i tion by which these obiects are attainedis shown in the accompanying drawings in which- Fig. l is a sectionthrough an extractor showing the means for securing place. A

Fig. 2 is an enlarged sectionthrough the cone showing the inner parts inelevation.

As shown in Fig. the shape of a truncated cone which is pretierably spuntrom copper and lated. The cone is closed at the top with abell shapedend and is provided with an aperture tor receiving the upper end ot arod 2. rthe rod 2 is threaded at the upper end and nut?) is threadedthereon,- a washer t being positioned on the nut 3 about the rod 2 asshown. This washer 4 supports a bell shaped metal disc 5 which conformsto the shape or" the u per end ot the conical shell l. is will e notedJtrom Fig. 2 the bell shaped disc 5 is positioned within and supportsthe upper end of the cone centrally on the rod 2, the rod 2 extendingthrough an aperture provided in the cone. A washer o is positioned overthe rod 2 on the exterior oir' the cone and a nut 7 isthreaded on theupper end oit the rod 2 so that the parts are bindingly secured betweenthe nuts 3 an the lower e the rod 2 is threaded into a nut 6 and the nut6 is provided with an enlarged threaded aperture 7 adapted to be'threaded ont/o the` threaded end 8 of a shaft 9 as shown in Fig. 1.'lhe nut 6 is provided with a dange l0 at the cone in that the has Isolidly be 2 a shell l is provided 1n 75 are Nil

be loaded with web the lower end which when threadedonto the end 8 ofthe shaft 9 engages the bottom of the basket or perforated receptacle11. This basket 11 is provided with a series of apertures 12 and iskeyed to the shaft 9 by a key 13 and as shown in Fig. vided with ashoulder 14 on which the portion 15 of the basket 11 seats, the enlargedportion of the shaft being rotatably mounted in the casing 16. To securethe cone in place the usual nut is removed from the threaded end 8 ofthe shaft 9 and the nut 6 is threaded thereon so that the flange 10thereof bindingly engages the portion 15 of the basket between theshoulder 14 of the shaft and the said iiange 10, the key'13 preventingrotation of the shaft in relation to the basket. At this time the rod orshaft 2 is threaded into the upper end of the nut 6 and the lock nut 17is threaded down tightly against the upper end of the nut 6 to lock therod from movement in relation to the nut 6. At this time the nut 3 isthreaded on to the upper end of the shaft 2 and the washer 4 and llsh-aped disc 5 are positioned thereon. The conical shell 1 is thenplaced over the end of the shaft 2 on the disc 5 so that the flange 18at the bottom of the cone engages the bottom of the basket. Should theflan e not engage the bottom of the basket proper y the cone is removedand the nut 3 is adjusted so as to allow the proper engagement at whichtime the washer 6 is positioned over the end of the shaft and the nut 7is turned down tightly to lock the parts in position at the upper end ofthe shaft between the nuts 3 and 7.

en this has been done the basket may clothes, the cone 1 assisting inspacing the clothes from the center of the basket and in loading thebasket i The,

evenly so that itis not out' of balance. cone l also prevents any of theclothes being positioned diametrically across the center of the basketand, when the basket is rotated at a high rate of speed by rotation atwhich time the water within the clothes due to thecentrifugal force isexpelled from the clothes through the apertures 12 .in the sides of thebasket. lin some extractors the shaft 9l is flush with the bottom of thebasket in which case a recess and threaded to receive 2 which is locked1n the recess by the lock nut 17. The basket may also be secured to theshaft 9 by a pin or other means beside the key 13.

In making the first cones for this purpose a true conical shell wasutilized and the nut 3 and bell shaped disc 5 were not u sed, but a nutsimilar to the nut 7 was utilized 7 Was turned down tightly 1 the shaft9 is prothe end of the shaft d and having a flange to force the loweredge of the shell into engagement with the bottom of the basket. Tosecure the shell solidly in place the nut which would draw the cone outof shape at the upper end and -very often cause the same to break. Fromthat construction the cone having the bell shaped upper end was devisedand the nut 3 and bell shaped disc were utilized so that the cone couldbe bindingly secured in place at the upper end and would notbreak whenbindingly secured in place. It will be thus seen from the constructionof the cone that no clothes can be positioned in the center of thebasket, thus preventing the same from being torn while the water isbeing extracted therefrom.

From the foregoing description it becomes evident that the device isvery simple and eflicient'in of order, is very strong, may be rigidlysecured in position, is of low manufacturing cost and provides a devicewhich accomplishes the objects described.

Having thus fully described my invention its utility and mode ofoperation what l claim and desire to secure by Letters Pattent of theUnited- 'States' is- 1. A detachable cone for use with a centrifugalextractor comprising the combination with a perforated basket having ashaft secured centrally thereto and provided with a 'threaded endextending into the basket, of a nut threaded onto the threaded end ofthe shaft and having a threaded recess in the upper end, a rod threadedinto the said recess, the said rod; supporting a bell shaped disc at theupper end, a conical shell having a flange at the lower edge adapted toengage the bottom of the basket, said shell tting over the bell shapeddisc at the upper end and a nut threaded on the upper end of the saidrod and adapted when turned up to bindingly secure the cone and the bellshaped disc together.

2. A detachable cone foruse with a centrifugal extractor comprising thecombination with a perforated basket having a rotatable shaft keyedthereto and provided with a threaded end extending into the basket, of anut threaded onto the threaded end of the shaft. and having a liangeadapted to engage the bottom of the basket, a rod secured tothe saidnut, a bell shaped isc carried by the upper end of the said rod, aconical shell fitting over the said disc adapted to engage the bottom ofthe basket, the disc fitting the upper end of the shell and a nut onthe. upper end of the rod binding the shell in position.

' 3. A detachable cone for use with a centrifugal extractor comprisingthe combination wit a perforated basket having a rotatable shaft keyedthereto and provided with a threaded end extending into the basket, of anut threaded ontothe threaded end of the shaft and having a ange adaptedto engage the bottom of the basket, a rod secured to the said nut, abell shaped dise carried by the upper end of the said rod, a conicalshell `fitting over the said disc and having a Hangs adapted to engagethe bottom of the basket, the dise fitting the lo upper end of thesheli, a nut on the upper end of the rod binding the shell in positionand means for adjustingx the position of the disc longitudinally of t erod.
